Core items

Phantom Dancer

+45% Attack Speed
+30% Critical Strike Chance
UNIQUE Passive - Spectral Waltz: While within 500 units of an enemy champion you can see, +12% Movement Speed and you can move through units.
UNIQUE Passive - Lament: The last champion hit deals 12% less damage to you (ends after 10 seconds of not hitting).

The Bloodthirster

+75 Attack Damage
UNIQUE Passive: +20% Life Steal
UNIQUE Passive: Your basic attacks can now overheal you. Excess life is stored as a shield that can block 50-350 damage, based on champion level.
This shield decays slowly if you haven't dealt or taken damage in the last 25 seconds.

Prepare B.F. Sword for your Infinity Edge and buy Guardian Angel if they really focused at you during teamfights. Last Whisper + Bloodthirster + Phantom Dancer = Deadly Cait. Last Whisper can ignore 35% of target's Armor as it increases your poking damage. Once you have Bloodthirster, Keep doing Final Blowing Minions as it increases life steal and damage each time you kill a minion. Phantom Dancer can increase your attack speed which you can kill your enemy a lot faster.

More Tips

*Caitlyn is the longest-ranged champion in the League, so keep your distance to melee champions and keep poking them basic attacks (You can also use 'Q' if caught on Yordle Snap Trap.
*Use 'E' towards an enemy so that you can slow them.
*Also, Don't forget to wards (Do not depend on the support)
*Always be the last one to join teamfights and just keep poking them (Can also use 'Q' if they were close to each other)
